KEY: N = data are nonexistent.
NOTES: Data from 1995-2000 and 2001-2003 are not comparable due to a methodology
change. Interruptions
of service include major and minor
mechanical failures. Since 2001, if the vehicle operator was able to fix the problem and return
the vehicle to service without assistance, the incident has not been
considered an interruption of service.
Other
generally includes automated guideway, Alaska
Railroad, cable car, ferryboat, inclined plane, jitney, trolleybus, aerial
tramway, and vanpool. However, aerial
tramway data are not included prior to 2003, Alaska Railroad data are not
included prior to 2001, and jitney data are not included in 2000 or
2001.
